Cryoglobulinemic vasculitis is most commonly observed in the setting of hepatitis C infection. However, many other etiologies have been identified as well. We herein report a case of cryoglobulinemic vasculitis in a 56-year-old male secondary to infective endocarditis. The patient presented with a five-week history of a painful, purpuric rash and was found to have positive blood cultures, elevated cryoglobulins, and vasculitis on histology. He recovered after treatment with intravenous antibiotics and steroids. Although rarely identified as a cause of cryoglobulinemic vasculitis, infective endocarditis must be considered on the differential diagnosis as a delay in treatment can worsen the prognosis for the patient.
冷球蛋白血症性血管炎最常见于丙型肝炎感染的情况下。然而,也已确定许多其他病因。我们在此报告一例56岁男性继发于感染性心内膜炎的冷球蛋白血症性血管炎病例。该患者有为期五周的疼痛性紫癜皮疹病史,血液培养呈阳性,冷球蛋白升高,组织学检查显示血管炎。经静脉抗生素和类固醇治疗后康复。尽管感染性心内膜炎很少被确定为冷球蛋白血症性血管炎的病因,但在鉴别诊断时必须考虑到,因为治疗延迟会使患者的预后恶化。
